Bring milk to the boil with sugar and rose water in a saucepan, reduce heat to ensure that milk doesnt overflow.

Dissolve the cornstarch in seperate bowl with a few tablwspoons of hot milk until smooth.

Add to saucepan and whisk well. Cook on medium heat for a few minutes until thickened. Remember it will thicken once it cools, so once it ooks like a thin custard it should be ready. Adjust sugar to taste during cooking time.
